Google’s stock-market value currently stands at about $249 billion, according to FactSet, which is good for fifth on the list of biggest U.S. companies, trailing Wal-Mart’s $251 billion market cap and Microsoft’s $257 market value.

Google shares have surged more than 30% since June, allowing the company to catapult past IBM on the market-cap list. IBM’s value stands at $234 billion.

While Google’s market cap has been rising quickly, it still has a long way to go before catching the top of the leaderboard.

Apple is by far the most valuable company, with a market cap of $645 billion. Last month it became the largest U.S. company ever, measured by stock-market value. Exxon Mobil rings in at second place with a market cap of $424 billion.
